Arsenic-sulfur speciation – a potential key to understanding arsenic accumulation and mobilisation in sulfidic aquifers of Bangladesh

DFG PL 302/2-1

Von 11/2006 bis 04/2008

Projektleiter: Britta Planer-Friedrich
Mitarbeiter: Cornelia Härtig, Heidi Lißner, Jörg Steinborn, Elke Süß

The objective of the project was to refine and extend the model for arsenic mobilization and fate in Bangladesh considering the potential impact of organic and sulfuric arsenic species. Specific goals were to investigate depth-dependent and seasonal changes with focus on changes in pH, redox potential and the redox-sensitive elements As, P, S, N, Fe, and Mn with a high temporal resolution, correlate these changes to sediment properties and model arsenic sorption and mobilization in sediments from different depths in laboratory batch and column experiments with special focus on the individual arsenic species and competition with phosphate.
